DILATOR Filed May 15, 1926 gwuanto'c Patented Mar. 11, 1930 WILLIAM J.KIRK, OF WELLSBURG, WEST VEBGINIA DILATOR Application filed. May 15,1926.

My invention relates to dilators, and particularly those of the kindadapted for use with rectal diseases or trouble. It has in view toprovide, in one instrument or implement, a hollow body portion forinsertion and massage manipulation, also for application of medication,and for heating, when desired, as hereinafter more fully described.

In the drawings showing certain preferred .10 embodiments of theinvention:

Fig. l is a View of the device in elevation;

Fig. 2 is a central longitudinal sectional view with the plunger andhandle extended;

Fig. 8 .is a similar view with the plunger screwed in to the limit ofits movement;

Fig. 4 is a similar View, showing-the plunger provided with a heatingelement;

Fig. 5 is a cross section on the line V, V, of Fig. 1;

Fig. ;6 is asectional detail view showing the closing plug for use witha chemical heater.

The body of the dilator consists of a hollow tubular member 2 having atapered insertion point 3, with the wall of the main body somewhatundulating as shown. The insertion point 3 is of a non-bulging diameter,substantially the same as the minimum diameter of member :2, and taperedforwardly beyond the next adjacent outward annular undulation, as shown.

The hollow terminal portion is adapted to contain a charge 4 ofmedicated substance for exudation through laterally arrangedperforations 5 by internal pressure on the medication 4.

Such pressure is effected by a plunger 6 forming the inner end of ahollow stem 7 which is screwed into the outer threaded end portion ofbody 2 by a threaded neck 8. The cooperating threads are of sufliclentlength to provide for ample plunger adpistment and forcing of themedication for several treatments.

Outwardly beyond the threaded portion 8, stem 7 is provided with aflared finger grasping terminal 9 of trumpet forn'lation, enabling theuser to take a firm hold thereof, either for manipulation of the dilatoras a whole for annular or longitudinal movement, as in massaging, or forrelative movement of Serial No. 109,280.

the plunger within the hollow body portion.

Terminal 9 also constitutes a thimble shaped socket a for insertion ofthe finger of the user or operator, thus facilitating easy manipulationof the dilator, without neces- 5 sitating grasping of it outwardly. Insuch construction the plug 17 may be set inwardly of the outer end ofthe finger terminal 9 as shown in Fig. 6, leaving the open tapered spacea for the finger as in the principal fig ures.

The body portion is also provided with an annular rounded edge ring 10having a front flat annular face at right angles to the longitudinalcenter of the dilator. Ring lO in such form provides a limitingabutment, and

reinforces the device as clearly shown.

When it is desired to include heating with the implement, a suitableheater ll, of the well known electrical resistance type, is in sorted inthe hollow interior 12 of stem 7 and connected by current supply wires13 to any source of current. In such construction the wires arepreferably extended through an outer holding plug 14 screwed as at 15into the flaring graspingterminal 9, with a separate connecting element16, the-device otherwise being substantially the same as above described.

I may also utilize any suitable chemical 0 heati substance or materialinstead of the electrical heater, by merely enclosing it within thehollow plunger by the endmost plug 17, of suitable tight construction.

With either construction the implement is 35 capable of merelymechanical use alone, for dilation or massage. without medication orwithout heat application. It is capable of use in the same generalmanner as dilators and for the same purpose, while providing by itsconstruction an easily handled and effective manipulator and expander.

When used with medication, the filling charge 4 may be exuded to anydesired degree by manipulation of the holding terminal to force theplunger 6 inwardly to any desired extent.

In the same way the device may be used either with. or withoutmedication, but with.

the application of internal heat, as provided for in the construction ofFig. 4.

The time of use or of application of medication, or heat, is easilywithin the control of the operator, and the various uses for treatmentof different diseases or troubles is entirely within the province of theoperator. The application of medication may be located at any desiredpoint merely by regulating the degree of insertion followed byadjustment of the plunger.

The construction and operation of the device will be readily understoodand appreciated by all those familar with this class of articles. It maybe made of various sizes and capacity as to reservoir content orotherwise changed or varied by the skilled mechanic. It will beunderstood also that while the device is preferably made of hard rubberor bakelite, it may be made of metal or other suitable material, but allsuch or other changes are to be considered as within the scope of thefollowing claims.

What I claim is:

1. A dilator consisting of a hollow elongated integral body circular incross section having a non-bulging tapered perforated minimum diameterend portion and a longitudinally undulating variable and maximumdiameter exterior and a rear annular flat faced limiting flange, and acontinuously integral interior hollow plunger having threaded connectionwith the outer end of the body.

2. A dilator consisting of a hollow elongated integral body circular incross section having a non-bulging tapered erforated forward endportion, a longitudinally undulat ing variable diameter middle exteriorand a rear annular limiting ring having a flat front face at rightangles to the longitudinal center of the dilator, a continuouslyintegral interior plunger having threaded connection with the outer endof the body, and an outermost extended interiorly tapered flaringtrumpet shaped grasping terminal.

3. A dilator consisting of a hollow elongated integral body circular incross section having a tapered perforated end portion and alongitudinally undulating variable diameter exterior, and a continuouslyintegral interior hollow plunger having threaded connection with theouter end of the body and provided at its inner end with a closed pistonlike terminal and at its outer end with an extended flaring interiorlytapered trumpet shaped grasping terminal.

4. A dilator consisting of a hollow elongated integral body circular incross section having a tapered perforated end portion and alongitudinally undulating variable diameter exterior, a continuouslyintegral interior hollow plunger having threaded connection with theouter end of the body and provided at its inner end with a closed pistonlike terminal and at its outer end with an extended flaring trumpetshaped grasping terminal, a heater in the hollow plunger, and a pluhaving threaded engagement within the flaring grasping terminalproviding a support for current supply conductors leading to the heater.

5. A dilator consisting of a hollow elongated integral body circular incross section having a tapered perforated end portion and alongitudinally undulating variable diameter exterior, a continuouslyintegral interior hollow plunger having threaded connection with theouter end of the body and provided at its inner end with a closed pistonlike terminal and at its outer end with an extended flaring interiorlytapered trumpet shaped grasping terminal, and a plug tightly securedwithin the flaring grasping termlnal and closing the interior of thehollow plun er.

6. In a dilator of the class describe the combination of a hollowelongated integral body circular in cross section having an interiorlyand exteriorly tapered end provided with a terminal and lateralperforatlons, and exudable substance within the tapered end, an outerannular rounded flat faced limiting collar and interior threads at theinside of the other end of the hollow body, and a hollow plunger havingan outer flaring grasping terminal in threaded engagement with saidthreads and provided with an inner piston terminal adapted to force theexudable substance through said perforations.

In testimony whereof I hereunto aflix my signature.

WILLIAM J. KIRK.
